EGG-TESTER.

` Specification of Letters Patent.

Patented Apr. y22, 1919.

Application filed October 2, 1918. Serial'No'. 256,576.

To all ywhom z' may concern v Be it known that I, THOMAS R. AUSTIN,

a citizen ofthe United Stat-es, residing atV Iconium, in the county ofSt, Clair and State of Missouri, have invented certain new and usefulImprovements in Egg-Testers, of which the following is a specification,reference being had to the accompanying drawings. 1.

This invention relates to certain improvements in egg testers, and it isan object of the invention to provide a device of this general characterhaving novel and improved means whereby the rays of the sun may beemployed to candle an egg. It 1s also an object of the invention toAprovide a novel and improved device of this general character which,when not in use, may be folded or compacted to occupy a minimum ofspace.

Another object of the invention 1s to provide a device of this generalcharacter including novel and improved means whereby rays of light,particularly thosey emitted from the sun, may be directed or reiiectedto penetrate a suitably (positioned egg in order to disclose all bloospecks which may be within` the egg, and also to determine the fertilityof the egg.

vThe invention consists in the details of construction and in thecombination `and arrangement of the several parts of my improved eggtester whereby certain important advantages are attained and the deviceren-v dered simpler, less expensive, and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely.claimed.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawings,wherein:

Figure 1 is a vertical sectional view taken through an egg testerconstructed in accordance with an embodiment of my invention andassembled for use; and

Fig. 2 is a fragmentary view partly in top plan andpartly in sectionillustrating the lowermost frame and the supporting means coactingtherewith for the reflector.

As disclosed in the accompanying drawings, A denotes a frame, preferablyoblong, and which has secured thereto and disposed over the outer facethereof a plate l of suitable material.

veins, spots, and

Hingedly connected as at. 2 with one end vof the frame A is a second.frame B of a form coincident with the configuration of the frame B, andsecured to and overlying the outer face of the frame B is a plate 3 ofopaque material, and which is provided at substantially its center withan egg receiving opening 4. I-Iingedly connected as at 5 with theopposite end portion of the frame B is a third frame C of the sameconfiguration as the frame B, and secured to and overlying the outerface of the frame C is a plate. 6 also of opaque material. `Connectingthe.

longitudinal sides of the frames B and C are Vthe iieXible curtains orlwalls 7 whereby a dark room is aorded when the frames B' and rC are inseparated relation.

Then not in use the frames A, B, and C are adapted to be folded one uponthe other with the flexible curtains or side walls 7 eX- 'tending, ifdesired, between the frames B and C. c

The resultant spaces between the frames A and B, when folded one uponthe other, af-

tening member 9 also coacting with the opposite end portion of the frameA for holding the frame C in its folded or closed position. The hingedend portion of the frame C is provided with a handV grasp 10 to affordmeans whereby the device may be readily transported.

In order to maintain the frame B in an open position relative to theframe A, I have pivotally engaged at one end portion with a side of theframe B a rigid arm or link 11. The opposite or free end portion of thearm or link 11 is adapted to seat within one of a series oflongitudinally spaced notches or recesses produced in the adjacent sideof the frame A. By this means it will be at once self-evident that theframe B may be held at dierent angles f of notches or recesses 15produced in the adjacent side of the frame B for the same purpose as hashereinbefore been stated relative to the arm or link 11 and the notchesor recesses l2.

M denotes a base. member adapted to be positioned upon the'plate 1 whenthe device is adjusted for use, and saidfmember con-A sists of twoelongated sections 16 hingedly connected at one endV as at 17 forrelative lateral swinging movement, and the op. posed faces of thesections 16 are provided with recesses18 which coact to afford a socketto receive a ball 19 carriedv by the lowei` end portion of a supporting,arm 20. Disposed through the free end portions of the sections 16 of thebase member M is al bolt 21 having threaded on its free endl portion ofits shank a thumb nut 22. Immediately adjacent the thumb nut 22 andmounted upon the bolt is a washer 23. Surroundingv the bolt 21y andinterposed between the washer 23 and the outer side face of theg axialvcenter. As herein disclosed the reflect'or27 is concavo-conveX in formwith its concave face upwardlydisposed 1n a direction away from theshank 26.

Upon proper adjustment of the' reiiectorV 27 relative to the opening 4in the pla-te 3,

the solar rays may be focused directly on an egg seated within thelopening 4 with the result that the operator may readily andconveniently candle the egg to discover all blood veins, spots, andspecks in the egg, and to determine the fertility thereof. It will alsobe understood that with the use of my improved egg tester,v the operatoris not confined but is at all times in a position to inhale fresh air.

-VVh'enthe device is. not in use the reiector 27 and itsy concomitantvparts may be readily separated so that the same can be stored within thecompartment or chamberaiforded between-the frames A and B when inconipacted'or folded relation.

I claim:

l. A reflecting device for an egg tester comprising' a base memberconsisting of two hingedly connectedsections, yielding means constantlyurging the sections one towardV the other, anarm having an end portionclamped betweenthe sections and capable of swinging movement, and areflector carried by said arm.

2. A. reliectin'gv device foran egg tester comprising abase memberconsisting of two hingedly connected sections, yielding means constantlyurging the sections one toward the other, an arm having an endl' portionclamped between the sections and capable of swinging movement, theopposite'end porf tion of the' arm 'being' provided' with.l a Y socket,andi a reiiectorprovided with a shank seat'able' within the socket ofthearm.
